B4J Question JShell Problem

Firpas · Oct 24, 2017

Hello to everybody

I`m trying to execute a command from my application through JShell but i can`t, however if i write it in system symbol window it run ok.

With this code:

B4X:

If File.Exists(FM.FotoDir, "test.mp4") Then
        File.Delete(FM.FotoDir, "test.mp4")
End If
       
Dim Sh As Shell
       
Sh.Initialize("Shell", File.Combine("C:\ffmpeg64\bin", "ffmpeg.exe"), Array As String(" -r 10", "-f image2", "-s 640x480", "-i "& File.Combine(FM.TempDir, "%08d.png"), "-vcodec libx264", "-crf 25", "-pix_fmt yuv420p " & File.Combine(FM.FotoDir, "test.mp4")))

Sh.WorkingDirectory = "C:\ffmpeg64"
Sh.Run(100)

Here is the result

It seems the option "-r 10" is passed as "r 10"

And with this code:

B4X:

If File.Exists(FM.FotoDir, "test.mp4") Then
       File.Delete(FM.FotoDir, "test.mp4")
 End If
       
Dim Sh As Shell
Sh.Initialize("Shell", File.Combine("C:\ffmpeg64\bin", "ffmpeg.exe") & " -r 10 -f image2 -s 640x480 -i "& File.Combine(FM.TempDir, "%08d.png")     & " -vcodec libx264 -crf 25 -pix_fmt yuv420p " & File.Combine(FM.FotoDir, "test.mp4"),Null)

Sh.WorkingDirectory = "C:\ffmpeg64"
Sh.Run(100)

The result is:

org.apache.commons.exec.ExecuteException: Execution failed (Exit value: -559038737. Caused by java.io.IOException: Cannot run program "C:\ffmpeg64\bin\ffmpeg.exe -r 10 -f image2 -s 640x480 -i C:\Users\Fran\AppData\Roaming\IpCam\Temp\%08d.png -vcodec libx264 -crf 25 -pix_fmt yuv420p C:\Users\Fran\AppData\Roaming\IpCam\Images\test.mp4" (in directory "C:\ffmpeg64"): CreateProcess error=2, El sistema no puede encontrar el archivo especificado)

But if i copy and paste the command "C:\ffmpeg64\bin\ffmpeg.exe -r 10 -f image2 -s 640x480 -i C:\Users\Fran\AppData\Roaming\IpCam\Temp\%08d.png -vcodec libx264 -crf 25 -pix_fmt yuv420p C:\Users\Fran\AppData\Roaming\IpCam\Images\test.mp4" in a system symbol window it run ok.

Thank in advance

I haven't used it for a while, but I think you need to pass all the arguments using the Arguments method.

B4X:

sh.Arguments =

Edit : Sorry, you need to pass them to the intialize method as a list.

B4X:

Dim L As List = Array As String("-r 10","-f image2") 'etc.

sh.Initialize("Shell",File.Combine("C:\ffmpeg64\bin", "ffmpeg.exe"),L)

Checked.
It isn't the problem

Thanks for you reply

Remove the space in front of the -r? You have " -r 10", try "-r 10".

Thank for your reply
The problem persists

"-pix_fmt yuv420p " & File.Combine(FM.FotoDir, "test.mp4")

I think this should be

B4X:

"-pix_fmt yuv420p", File.Combine(FM.FotoDir, "test.mp4")

making it

B4X:

Sh.Initialize("Shell", File.Combine("C:\ffmpeg64\bin", "ffmpeg.exe"), Array As String("-r 10", "-f image2", "-s 640x480", "-i "& File.Combine(FM.TempDir, "%08d.png"), "-vcodec libx264", "-crf 25", "-pix_fmt yuv420p", File.Combine(FM.FotoDir, "test.mp4")))

Yes, i know the destination file is another option.
I've tried as you say, but it does not work.

Here is the log:

It's this

B4X:

Array As String("-r","10", "-f", "image2", "-s", "640x480", "-i", File.Combine(File.DirTemp, "%08d.png"), "-vcodec", "libx264", "-crf", "25", "-pix_fmt", "yuv420p", File.Combine(File.DirApp, "test.mp4")

Anytime you have a space between parameters, even if they are values for the previous parameter, they are separate parameters. And no, it's not just FFmpeg (I also tried GraphicsMagick) and it's not just the new 1.5 version of JShell (the same happens with 1.3). In the end this really makes sense if you think about it.

Ok. Solved!
Now run OK!

Thank you for your collaboration.
